As for an intuitive explanation, here we would like to resort to Maxwell's demon. Based on both thermodynamics [1]} and information theory [2]}, the recognized explication for how the demon works is that the demon has to know each molecule's velocity in order to perform his task, while such knowledge (or to be called information) itself is negative entropy, in other words in the physical reality, entropy must increase when the demon attempts to acquire new knowledge about a molecule's velocity by whatever means. Hence the demon's seemingly subjective knowledge as a static mental state actually carries physically objective negative entropy, exactly because the demon is able to act dynamically according to his knowledge and thus influence the physical world. Therefore, this well known thought experiment strongly defenses our metaphysical and epistemological thesis that knowledge is essentially dynamic.
